Multifunction polarization controller

General Photonics Multifunction Polarizer

The state of polarization (SOP) control of an optical signal was never easier < p>

The Multifunction Polarizer MPC-201 has four modes of operation for complete control of the polarization.

• Polarization scrambling with adjustable scrambling speed
• Manual adjustment of polarization
• modulation of polarization
• Externally triggered setting of random polarization states

The different polarization scrambling modes change the polarization state (SOP) as follows:

Tornado mode:

The polarization states are along a spiral path on the Poincaré sphere continuously traversing the reference axis is statistical or rotating. Application: System Stress Test

Rayleigh mode:

The polarization states are traversed so that an SOP distribution is created Mimics the behavior of a real fiber optic link.

Triangle mode:

Creates a continuous track with uniform coverage of polarization states the Poincaré sphere for PDL measurements

Random distribution:

The discrete polarization states are randomly driven with a uniform hop rate. The overall distribution is uniform

SOP Modulation Modus:

Modulations-Modus

Manual Modus:

he internal polarization controllers are manually adjusted by adjusting the input voltage individual polarization axes can be controlled. This can be done via the control elements on the device or computer-controlled via the interfaces

Trigger-Modus:

Random discrete polarization states are generated upon application of a trigger signal. With every pulse the polarization controller jumps to the next discrete random polarization state. This is especially for Applications that require synchronization with other measuring equipment, such as recirculating Loop applications.
